Removed query portion of repository.json.

I couldn't really find documentation about this change, but the prior commit (https://github.com/fcrepo4/fcrepo4/commit/3c127128ec71919200e6e687444b9709700ee529) appeared to unceremoniously remove the query section of this config, so I suspect the default behavior in modeshape 4 is acceptable.

The one change fixes fcrepo-webapp-auth.war in fcrepo-webapp/, the other fixes anywhere (nowhere?) where the clustered config is used.
